at the'hub thereof for the winding of the film on the reel. 5 I

With this object in view my invention consists in certain features ofnovelty in the construction, combination and arrangement ,of parts bywhich the said object and certain other objects, hereinafter appearing,are

effected, all as fully described with reference to the accompanyingdrawing and more particularly pointed out in the claims.

In the said drawing Figure 1 is a side elevation of a motion picturefilm reel embodying my invention.

Figure 2 .is a partial edgewise elevation of the same with parts brokenaway and in section on the line 2-2 of Figure 1;

Figure 3 is a face View of a portion of a motion picture film adapted tobe wound on the reel;

Figure 4 is a face view of one of the spring washers of the device,hereinafter described; and

Figure 5 is an enlargedsection on the line 5-5 of Figure 4.

- Like characters of reference indicate like parts in the several views.

Referring to the drawing, 1 and 2 designate respective parallel sideplates of the reel, which are preferably formed of sheet metal, andstruck from the metal of these plates are hub segments 3 spaced aboutthe 4 axis of the reel. The segments 3 of the plates.

land 2 alternate to form the hub of the reel, 1

and the outer ends of these segments are reduced, as designated at 4,and. ass through apertures through adjacent si e plates and are rivetedover on the outer faces of the side plates, as designated at 5, in theassembly of the reel. See Figures 1 and 2.

The segments 3 of the plate 1 are adj acently spaced from the plate 2about the end por-- tlons 4 thereof, thereby forming interme-v fromabout said portion, and a spring mem- 1928. Serial, No. 297,296.

diately reduced portions 6 elongated .in cross section correspondingwith the eriphery of the hub and forming shoulders facing and'adjacently spaced from the plate 2.

Spring washers 8, having apertures 9 thereof. elongated correspondingwith the portions 6, are bent or angled facewise corresponding with thelengths of these apertures and in the direction of the adjacent plate 2,and. are engaged on. thie;portion's 6 and engage with the plate 2 andthe shoulders 7 to maintain the washers in proper position. See Figures1, 2, 4 and 5.

The s acing of the plates 1 and 2 is such that a lm 10 freely engagesvbetween the same, but the washers 8 reduce the effective width of thisspacing adjacent the hub in a tapering manner toward the hub, '50 thatthe film is frictionally engaged ed ewise at the hub between the springs8 an the plate 1 '10 to hold the end of the film on the reel for thewinding of the film thereon, the yielding of the springs 8 permittingthe fi1m -to lie flat on the hub wh1le maintainin edgewisefrictional'engagement with the It will be observed that the film may beeasily and conveniently engaged and disengaged between the springwashers 8 and the plate 1 and that this enga ement may be convenientlyefiected in the ark, thus adapting the reel particularly to use onmotion picture projecting machines.

While I have described and shown the preferred embodiment of myinvention I do not wish to be limited to' the precise details of Iconstruction as changes may readily be made without departing from thespirit of my invention, but having thus described my invention, I claimas new and desire to secure by Letters Patent the following:

1. In a film reel the combination of spaced side lates and a hubextending therebetween, said ub having a portion thereof extending toone of said lates and being spaced thereher provided with an openingengaged on said portion and adapted to engage a on said hub edgewise forfrictional engagement thereof.

2. In a film reel the combination of spaced side lates and a hubextending therebetween,

said ub having-a portion thereof elongated in cross-section peripherallyof the hub and extending to one of said plates, said hub being spacedfrom said plate about said portion and forming a shoulder facing saidplate,and a spring member provided with an elongated aperture engaged onsaid hub portion and angled facewise to engage said shoulder at saidaperture and to engage said plate with its edge portion.

3. In a sheet metal film reel the combinaing there etween, said hubhaving a portion thereof extending to one of said plates and 1 thenreduced and passing through an aperture through this plate and rivetedover on the outer face of this, plate, said hub being spaced from thisplate about said portion and forming an intermediately reduced'portionand a shoulder facing and spaced from said plate, and a spring washerengaged on said intermediately reduced portion and angled facewisetoengage said shoulder at' its aperture and to engage said plate with itsedge pprtion. 4. a sheet metal film reel the combination of spaced sideplates and a hub extending therebetween, said hub having a portionthereof extending to one of said plates and then reduced and passingthrough an apertion of s aced side plates and a hub extendv ture throughthis plate and riveted over on the outer ace of this plate, said hubbeing spaced from said plate about said portion and forming anintermediately reduced portionelongated in cross section peripherally ofthe hub and forming a shoulder facing and spaced from said plate, and aspring washer having its aperture elongated and engaged on saidintermediately reduced portion and angled facewise in a plane transverseto the longitudinal extent of said aperture to ention of side plateshaving portions spaced gage said shoulder at its aperture and to en-'gage said plate with its edge portion.

5. In a sheet metal film reel the combinaabout the axes thereof struckfrom the metal thereofand forming hub segments, the segments ofone ofsaid plates alternating with the segments of the other and each segmenthaving its outer end reduced and.

passing through an aperture through the adjacent plate and riveted overon the outer face of the adjacent plate, the segments of one ofsaidplates being spaced from the other late about said portions thereof andforming intermediately reduced portions elongated in cross section periherally of the hub and forming shoul ers facing and spaced from saidother plate, and

. spring washershaving their apertures elongated and engaged on saidintermediately reduced portions and angled facewise in planes transverseto the longitudinal extent of their apertures to engage said shoulders
